Debug inbound queue in ECC from APO

Hi Experts,

I americium incapable to debug the inbound queue successful SAP ECC for a process executed from APO with transaction
/N/SAPAPO/BOP.

The inbound queue CF* ne'er appears successful SAP ECC.

I performed the pursuing steps:

1. Unregistered CF* successful SAP ECC successful transaction SMQR
   

2. Enabled debugging successful SAP APO successful transaction /SAPAPO/C4
   

3. Executed the script successful transaction /N/SAPAPO/BOP

   

4. Checked SMQ1 and the CF* queue appears successful APO's outbound queue

   

5. Executed the outbound queue successful APO

   

6. Checked SMQ2 successful ECC and couldn't find the CF* inbound queue

   

I besides tried forcing an mistake by keeping the income bid unfastened successful ECC, but the mistake returns successful APO's outbound queue erstwhile I request it to look successful ECC's inbound queue.

Why doesn't the inbound queue look successful ECC?

Thank you precise much.
